Thisis accomplished autonmtice lly as follows. i-The outerend-QQ of thefilm. from the reserve; roll '7 -9: is laid l upon the a anvil 1-6awithya. .met slli c fastener .23; projecting through it having. thesharp ends. 24; gprojecting upwardly. The

die 15, carried by n plunger 25,: is normally held raised-layuplightspring. 26', but mey be caused tostrike the. fastenerhbencting.over the sharp ends thereof (thus uniting. the film hands)- by 1 agravity .uctustcd striker, his striker. :1 hall,"isgwnormally held. bya.lutclrl which may betrippedhy .the fil n band F from the supply reel,as will be hereinafter described. The striker 27' falls upon the end 28of the die causing it to function, falling through the guideway 29.After depressing die 15, the striker rolls down the exit passage 30which obviously will admit the ball when the die is depressed.

This permits the spring 26 to quickly raise die 15 so that the filmuniting operation consumes very little time, being almost instantaneous.The striker can then be removed through the opening 31, and repositionedthrough the mouth 32 of the guiding tube 29. In order to trip the latchmember 28 the following mechanism is used. The film. band F passes overthe twin sprockets 12 and 13, as before described, the reason for thisbeing that the short length of film 33 is supported by the sprockets; Onthis length of film theactuating roller 34 is held in the position inFig. 1, wherein it maintains the bell crank lever 35 in an operativeposition. Roller 34 is supported on an end 36 of the lever 35 and theother end 37 is adapted to strike the tripping member 38 when the filmend reaches roller'12 permitting roller 34 to swing! in the direction ofthe arrow, Fig. 1. The latch 28 is pivoted at 39 to the frame. The end10 of this member contacts with the tripping member 38, which may swingabout pivot 4L1. As part 37 strikes 38 it is swung in the direction ofthe arrow Fig. 5, permitting latch 28 to swing in the direction of thearrow, and allowing the striking member 27 to fall. The cam surface 42contacting with part 43 when the parts are being set swings member 38about its pivot so latch 28 may return to its set position. The weightof the tripping member 38 normally holds it in the position shown. V I 1e As will be seen'fro-m Fig. 2, sprockets 12 and 13 are carried by aframe 45 having an operating handle 46 which may be used for removing orinserting the squared plug 47 into aperture 48, as the removal of thesesprockets greatly facilitate positioning the film from the reserve tothe supply position.

It is necessary to cause'the film to momentarily pause just as the die15 strikes the anvil 16 when the film ends are clipped together, thisbeing accomplished by a flexibly driven sprocket 19. As may be seen inFig. 3, this is mounted on a shaft 50, supported by bearings 51 ofbracket 52.

A sprocket wheel 53 is mounted to turn freely on shaft 50, being movedconstantly by a chain 54. The sprocket moves a cup shaped member 55, towhich is fastened an end 56 of aspring 57. The other end 58 is affixedto shaft 50, so that the shaft derives its entire movement through thespring, which is partially tensioned when driving. A ratchet wheel 59 isatfixed to the shaft and may be engaged a pawl 60 to stop the shaftmomentarily, thus increasing the tension on spring 57. When released,the spring will drive shaft faster than the normal driving speed for amoment, so that the only effect on the movement of the film band is tovary, for the moment, the position of the floating roller 20, assprocket 21 drives the film band from this variable supply constantly atan even speed into the machine.

Pawl pivoted at 61 is actuated through the arm 62, which engages a pin63 on the die 15, so that as the die approaches the anvil pawl 60 willmomentarily engage ratchet wheel 59, thus stopping the sprocketoperation, he moves the roll from hook 5 up incline 6 to hook 7. Thisdoes not in any way disturb the feeding of the film which continuesduring the operation. Having previously removed sprockets 12 and 13 bythe handle 16, these are again positioned with the film running overthem so that roller 3a is thus returned to its operative position andwith it bell crank lever 35 is also moved to operative position, afterreturning the latch 28 to aposition in which the striker 27 is heldready for the next operation. After the operator places a new reserveroll in place in hook 5 and threads the end of the film over thefastener on anvil 16, he may attend other machines.

Having thus described my invention,

,what I claim as new and desire to secure by Letters Patent is:

1. A film supplying mechanism comprising, a reel of supply film, meansfor drawing film from said reel, a reel of reserve film, and meanscontrolled by the supply film for connecting the outer end of saidreserve film with the final end of said supply film. i

2-. A mechanism as in claim 1, in which the connecting means attaches afastener to said ends of said films.

3. A mechanism as in claim 1 in which the connecting means clinches apronged metal fastener in said ends of said films.

4. A film supplying mechanism compris ing,'a reel of supply film, asprocket for drawing film from said reel, a driving element and aflexible member connecting the driving element and the sprocket, a reelof reserve film, means including the flexible member for permitting thesprocket to pause momentarily, whereby a dwell is produced in saiddrawing, and means for automatically connecting the outer end of saidreserve film with the final end of said supply film during said dwell.

5. A film supplying mechanism comprising, a reel of supply film, meansfor drawing film from said reel, a reel of reserve film, means forproducing a dwell in said drawing, means for attaching together theouter end of said reserve film and the final end of said supply filmduring said dwell, both of said means being controlled by the supplyfilm.

6. A film supplying mechanism comprising a reel of supply film, meansfor conducting film from said reel, along a path, a reel of reservefilm, a support adjacent said path for holding the outer end of saidreserve film and a bendable fastening element attached to the film, andmeans cooperating with said support for automatically connecting saidouter end of the reserve film to the final end of said supply film bybending said fastening element over upon the supply film.

i. A film supplying mechanism comprising a reel of supply film, meansfor conducting film from said reel along a path, a reel of reserve film,a support adjacent said path for holding the outer end of said reservefilm and a metallic clip, and means cooperating with sald support forautoinatically completing a connection between saidouter end of thereserve film and said final end of the supply film by clinching saidclip.

8. A film supplying mechanism comprising a reel of supply film, meansfor conducting film from said reel along a path, a reel of reserve film,film fastening devices adjacent said path, a source of energy foractuating said devices, and means controlled by the approachof the finalend'of said supply film for releasing energy from said source to actuatesaid devices to fasten said final end of the supply film to the outerendof the-reserve film. V I

9. A film supplying mechanism comprising a reel of supply film, meansfor conducting film from said reel along a path, a reel of supply film,film fastening devices in operative position With respect to said path,the outer end of said reserve film and a fastening element heingsupported in said devices, and means controlled by the approach of'thefinal end of said supply film for actuating said devices to apply saidele ment in fastening relation tosaid final end of the supply film andsaid outer end of said reserve film.
